CVE-2009-1979

86
FAUCET Score

CVE-2009-1979 is an unspecified vulnerability in the Network Authentication component of Oracle Database versions 10.1.0.5 and 10.2.0.4. It carries a critical CVSS score of 10.0, indicating a severe risk of compromise to confidentiality, integrity, and availability, accessible remotely with low attack complexity and no authentication required. While Oracle initially provided limited details, independent research suggests it involves improper validation of the AUTH_SESSKEY parameter length, potentially leading to arbitrary code execution. Exploit code, including a Metasploit module, is publicly available, yet there is no indication of active exploitation, and it has received minimal community discussion or media coverage.
